TRAFFIC-SIGNAL. 7

To all whom it may concern Be it known that I, DANIEL W. Gone, a

citizen of the United States, residing at- Bufl'alo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Traffic-Signals, of which the following is a specification, reference being had to the accompanying drawings.

This invention'relates to traflic signals and pertains more particularly to a device of this general character especially designed and adapted for use at street crossings, and it is an object of the invention to provide a novel and improved device of this general character which may be readily and conveniently operated manually by the traflic ofiicer. I 7

It is also an object of the invention to pro vide a novel and improved device of this general character including a semaphore or indicating device adapted to be moved or shifted into the requisite indicating positions, together with audible means operating during the'periods of movement of the semaphore or indicating member, so that the traffic oflic'er is relieved of the necessit of blowing a whistle, as is now generally one.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved trafiic signal whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient. and advantageous for use, as will be hereinafter more fully set forth. y

The novel features of my invention will hereinafter be definitely claimed.

.In order that my inventionmay be the better understood, I will now proceed to de-- scribe the samewith reference to the accompanying drawings, wherein n 7 Figure 1 is a view in perspectlve of a signal constructed in accordance with an embodiment of my invention;

view taken through the casing and the piston working therein.

As disclosed in the accompanying drawings, B denotes a base adapted to be rested at a proper position at a street crossing or the like, and extending upwardly from the central portion of the base B is a standard S. The upper end of the standard S at the axial center thereof, is provided with an elongated socket 1, in which is received the lower end portion of a vertically disposed standard or rod R. The standard or rod R is preferably circular in cross section with the socket 1 correspondingly formed, so that the standard or rod B may be readily and conveniently rocked or rotated.

M denotes a semaphore or indicating member'preferably comprising a rectangular frame affording the vertically disposed side faces 2 upon which are suitably arranged the indications 3, such as Go and Stop. The opposed indications 3 are similar, so that upon a quarter turn of the standard or rod R, as generally required at a street crossing or intersection, the same indication or warning will be exposed to the trafiic on the same street at opposite sides of the intersection.

The semaphore or member M, as herein disclosed, has a framecentrally intersected by a cross member 4, provided midway its length with a sleeve or socket 5 to receive the upper end portion of the standard or rod R, and suitably locked thereto, so that the semaphore or member M will rotate in unison with, and in the same general direction as the standard or rod R.

6 denotes an operating arm provided at one end with a sleeve or collar 6 through which the standard or rod R extends, and said collar 6 is suitably locked to the standard or rod R, and preferably through the instrumentality of the binding screws 7 threading said collar 6*, and engaging the standard or rod R. The outer extremity of the arm 5 is provided with a handle or 7 whereby the requisite rocking or rotation of the standard or rod R may be conveniently effected by the traffic oihcer.

C denotes a casing in top plan of the form of a sector of a circle, with the end walls 9 arranged substantially on an angle of 90, and the inner vertical margins of said side ber 10. The member lO extends below the bottom wall 11 of the casing C, said lower extended portion constitutes asplit sleeve or barrel 12, having its edges defined by the outstanding flanges ll with which v coact the binding members 15. The upper portion of the standard S extends within the split sleeve or barrel 12, and which sleeve or barrel is clamped to said standard S, whereby the casing C is supported in a stationary position with respect to'the device in its entirety.

The: bottom wall '11 and the top wall '16 of the casing 'C at the apices thereof, are

provided with the openings 17 through which the standard orrod R is loosely directed.

I also find it of advantage to interpose be tween the top wall 16 of the casing C and'the collar 6, the'spacing sleeve 18 surround- .ingthe standard or rod R and riveted or otherwise fixed to the top wall 16 of the casin C. A denotes a piston arranged within the casing C and radiating from the portion of the standard or rod It within said casing.

The marginal portions of the piston contact with thebottom wall 11 and the top wall- 16 of the casing C, and also with the outer or arcuate wall 19, so that when the standard or rod R is rocked, the air at the side of the piston P, toward wh ch said piston is moving, 1s placed under pressure to operate the whistle WV or other pneumatic I si al.-

* ach of the side walls 9 of the casing C is provided with an opening 20, in which is 'suitably'engaged an end portion of a whistle W or other pneumatic signal, so that i. the same will be caused to operate upon movement'of the piston P in a direction thereto. Eachof the side walls 9 is also pro- 1 vided with an induction port 21 with which coacts a check valve22, herein disclosed as i of a flap type. 'VVhen the piston P is mov ing in one direction air is dra'wninto the casing C at the side of the piston P, in which said piston is moving. The check valve 22, at the side of the piston P in'the direction of its travel,-is maintained closed by the air compressedby the piston P in such movement. I V

As-herein disclosed, the piston P comprises a metallic sheet of requisite dimen-' 'sions folde'd'centrally upon itself, to

pro vide the overlying'portions 24. The folded portion of the sheet is cylindrical in form to. provide a barrel 25 through which the standard or rod 'R extends, and said sheet,

or more'particularlythe piston P, is clamped to the standard or rod Rby the binding members 26. V

' Interposed between the overlying portions 24 are the'laminations 27 of suitable material, and the marginal portions of'said lami- Ynations extend beyond the upper and lower and'the outer vertical margins of the pis- .ton Pa distance sufficient for liberal contact 2 with the bottom wallll, the top wall 16 and the arcuate wall 19;

-As-, is clearly illustrated in the accompanying drawings, the extended portions 17 of thelaminations 27 are oppositelydirected. The laminations 27 can be of any desired 'material, such-:asfelt,'sheet rubber, leather and the like. It is alsb to be noted that the side walls 9 are ;so constructed that when the piston P is at the limit ofits move- 'ment iii'either direction, no interference or obstruction is offered by the check valve 22 and the connected portions of' the whistles'W.'

To further facilitate the desired movement ofthe piston P with the standard or rod R, the barrel 25 may be looked, as at 28, directly with the standard orrod R.

From the foregoing description it is thou ht to beobvious that a traffic si nal t3 23 construction in accordanoewith my invention is particularly well. adapted for use and formation of the'sev'eral parts herein shown in carrying out my invention in practice except as hereinafter-claimed. Iclaima v 1.
